Last year craigslist deployed MongoDB for its multi-billion document posting archive, largely due to its schema-free nature and built-in sharding and replica sets. Since then we've looked at it for other projects--specifically high-volume and multi-datacenter. In the process we've learned more about where other features do and don't work so well, including replication, capped collections, and compound indexes. This presentation wil recap what's worked well for us and discuss the other issues we ran into for new projects, as well as possible improvements in the the design or enhancements for MongoDB.
